amhoime sp. n., with peculiarly lonc^ and slender tentacles ; Plenrohrachia 

 striata sp. n., which closely resembles F. pigmentata from the ]\Ialayan 

 Archipelago ; and Gamsha {Lampelia) elegans g. et sp. n., which cannot 

 be included in any of the known orders. The new order proposed is 

 named Ganeshid^, and the diagnosis reads :— " Flattened in the tenta- 

 cular axis ; provided with annular canal, into which the stomach-vessels 

 and the four subtentacular vessels open ; the inter-radial and tentacular 

 vessels spring directly from the funnel ; tentacular sheaths are present."

Fresh-water Sponges of India.*— N. Annandale describes five new 

 species of sponge from the Museum tank, Calcutta — SpongilJa proUferms, 

 S. crassissima, EpJujdatia indica, Trochospongilla latouchiana, and T. 

 phiUottiana. He records Spongilla carteri and Ephydatia rohusta from 

 Himalayan tarns, and gives a list of the Indian forms. 



Protozoa. 



New Fresh-water Rhizopod.t — S. Awerinzew reports on fresh-water 

 Protozoa from Waigatsch Island (Murman coast). He discusses 17 

 species and a new form, Schaudinmda arcelloides g. et sp. n., with a retort- 

 like shell (like Campascus triqueter Penard), and with a quite superficial 

 resemblance in shell structure to Arcella. 



Fusulina.|— H. Yabe makes a contribution to our knowledge of the 

 Foraminif era genus Fusulina, which he divides into four sub-genera : — 

 (1) Fusulina s. str., type F. cylindrica Fischer ; (2) Sckwagerina, type 

 S. princeps Ehrenberg ; (3) DoUoUna, type D. lepida Schwager ; and 

 Neoschioagerina n. subg., type N. cratimlifera Schwager. 



New Radiolarian Family.§ — A. Popofsky has found amongst the 

 material of the German South Polar Expedition representatives of a new 

 Radiolarian family, embracing two new genera. This family, termed 

 Lithacanthid^e, is distinguished by possessing four or six thick spines, 

 radiating from a point at right angles to one another, and forming a 

 single skeletal piece. There are upwardly-directed soft flap-like bodies 

 upon the spines. There are also described two species of a new genus, 

 Conostylus, belonging to the family Thalassothamnidffi. 



Parasitic Euglen0e.il — W. A. Haswell points out that Fughna-like 

 forms may live as endo-parasites in the cells of Turbellarians. In 1892 

 he noted such a case in a Rhabdocoele, and he has found another in a 

 Mesostomid. The parasites were seen moving about within the pro- 

 toplasm of certain of the cells of their hosts, often pushing aside the 

 nucleus, or displacing protoplasmic filaments. They were abundant 

 among the spermatozoa in the vasa deferentia and vesicula seminalis. 

 In sections they were found within the cells of the digestive epithelium, 

 but most abundantly in the spaces between the gut and the body-wall.
